Auto Turn-Off for Personal Hotspot
If your Oppo phone keeps its Wi-Fi hotspot running long after every device has disconnected, it drains the battery for no reason. ColorOS includes a setting that shuts the hotspot down automatically once nothing has used it for a while. Without that toggle enabled, the hotspot stays active until you switch it off by hand.
Move Apps and Files to an SD Card
When internal storage on your Oppo phone runs low, photos, videos, and even some apps stay stuck on the device even though an SD card is installed. Coloros includes a built-in transfer tool, but it only works with certain file types and not every app is eligible for the move. Knowing which data can actually shift to the memory card helps you free up space without deleting anything you need.
Connect to Wi-Fi via WPS
Typing a long Wi-Fi password on a small keyboard gets old fast, especially with random character strings. If your router supports WPS, your Oppo phone can skip that step entirely and pair using a physical button push instead. This only works while both devices are actively listening for the WPS handshake at the same time.
Turn Keyboard Sound On or Off
Typing without any click sound, or suddenly hearing it after a system update, can be confusing since Oppo phones don't have a dedicated keyboard sound toggle inside ColorOS itself. The setting actually lives inside the Gboard app that most Oppo devices use by default. On many devices this sound is turned off from the start, leaving you unsure where to look for it.
Personal Hotspot: Change Name, Password and Band
Your Oppo phone activates a personal hotspot with a generic name and a default password, which is fine for a quick test but risky for daily use. If you want other people to recognize your hotspot easily or you need a stronger password, you have to adjust these settings yourself.
Allow Repeated Calls in Do Not Disturb
Urgent calls from the same number can go straight to silence when Do Not Disturb is active on your Oppo phone. ColorOS has a built-in exception that lets a second call within three minutes ring through, but it stays switched off until you turn it on yourself. Without it, every call gets muted the same way, no matter how often someone tries to reach you.
Add and Manage Words in the Personal Dictionary
If your Oppo keyboard keeps autocorrecting names, abbreviations, or technical terms you actually want it to remember, the built-in Personal dictionary is likely empty or missing those entries. ColorOS lets you store custom words and optional shortcuts so the keyboard suggests them instead of fighting you. This mainly affects people who type industry jargon, nicknames, or non-standard spellings regularly.
Turn Location (GPS) On or Off
When Smart Lock or Find My Mobile suddenly stops working on your Oppo phone, the location service is often the reason. Many apps also keep asking for GPS access even though you thought you had turned it off completely. Location tracking on ColorOS can be controlled system-wide or per app, and mixing up the two settings causes most of the confusion.
Block or Unblock a Contact
If a contact keeps calling or texting you and you want it to stop, blocking them cuts off calls and messages without deleting the contact. On Oppo phones this option sits inside the Contacts app rather than a dedicated blocklist screen, so it is easy to overlook. Unblocking later restores calls and texts from that number right away.
Remove a Folder from the Home Screen
Deleting a folder on your Oppo phone can go two ways: either the folder disappears together with every app icon inside it, or only the folder itself is dissolved and the apps land back on the home screen. Mixing up these two options often leads to accidentally losing apps you actually wanted to keep.
Add Another Fingerprint
If your Oppo phone only recognizes one finger, unlocking fails whenever that hand is wet, bandaged or busy holding something. Password & biometrics stores just the first scan by default, so app locks and mobile payments depend on that single print. Adding a second or third fingerprint, even from another person in the household, removes that single point of failure.
Turn Assisted Dialing (Roaming Assistant) On or Off
Calling contacts while traveling can fail on an Oppo phone because Assisted Dialing quietly inserts a country code you never asked for. This roaming assistant reacts whenever the network detects you outside your home country, even for numbers that would normally dial fine without a prefix. If that auto-added code breaks the call or reaches the wrong number, the fix is to switch the feature off and dial manually.
Set Up a VPN Connection
If your company or university hands you server details instead of a ready-made VPN app, your Oppo phone needs a manual profile entered directly in the system settings. Without the right protocol, server address and login data, the connection fails silently or drops right after you save it. This is different from installing a VPN app from the Play Store, which handles the setup on its own.
Create a Photo Album
When photos and screenshots keep piling up in one long timeline, finding a specific shot becomes a scroll marathon. The Gallery app on Oppo phones lets you group images and clips into albums, but ColorOS keeps the feature basic. You cannot pick a cover image, rename categories after the fact in every version, or nest one album inside another.
Turn Airplane Mode On or Off
If your Oppo phone will not connect to a network, WLAN, or Bluetooth device, Airplane mode might already be running in the background. Turning it on cuts mobile signal, WLAN, Bluetooth and NFC at once, which is useful on a plane but confusing when it happens by accident. Switching it off again does not restore every connection automatically, since only the settings you had active before get reloaded.
Enable Vibration in Silent Mode
Switching your Oppo to silent mode also kills the vibration, so you miss calls and messages without any signal at all. ColorOS does not have a separate vibrate mode like stock Android, so silent and vibrate are tied together unless you change one setting. Once you know where to look, you can keep your phone quiet but still feel it buzz.
Turn Grid Lines On or Off in Camera
Framing a landscape shot without a horizon reference makes tilted photos easy to miss. On many Oppo phones the camera grid overlay is switched off by default, so there is no composition guide in the viewfinder until you turn it on. Photo and video mode also handle this setting separately, which causes confusion when the grid shows up in one mode but not the other.
Turn On/Off Contact Suggestions in Messages
Typing a name into a message on an Oppo phone should pull up matching contact details automatically, but nothing shows up. This happens because the 'Suggest Contacts' feature inside the keyboard settings is switched off by default, even though the contact itself is saved correctly on the device.
Change Camera Storage Location
If new photos on your Oppo phone keep filling up internal storage even though a memory card is inserted, the camera app is likely still set to save shots to the device only. This becomes a problem once internal storage runs low and you cannot move existing photos automatically. Switching the preferred save target inside the camera settings fixes this without touching your gallery app.
Turn Off TalkBack (Accessibility)
If TalkBack is running on your Oppo phone, a single tap only selects an item and reads it aloud instead of opening it. Every action now needs a confirming second tap, which makes even switching TalkBack off feel out of reach. This select-then-confirm control catches most users off guard exactly when they try to disable the feature.
Allow or Deny Apps to Modify System Settings
If an app suddenly asks for permission to modify system settings, it usually wants to adjust things like your ringtone, brightness, or wallpaper, not your lock screen or passwords. On ColorOS this permission sits deep inside the special app access menu, so most users never find it on their own. Without it, some apps fail silently when they try to change these settings automatically.
Set Alarm Ring Duration
If your Oppo phone's alarm cuts off after just 5 minutes and you keep sleeping through it, the ring duration is still on the default setting. You can stretch it up to 30 minutes or shorten it to as little as 1 minute, depending on how deep a sleeper you are.
Customize Smart Sidebar Quick Access
If your Oppo's Smart Sidebar is packed with tools you never open, or missing the one app shortcut you actually need, the Quick access list needs an edit. The sidebar mixes three shortcut types: Quick Tools like screenshot or screen recording, Quick Apps that open in a floating window, and plain App shortcuts. Left unedited, you keep swiping past icons that only get in the way.
Change Ringtone
Stuck with the same default ringtone on your Oppo phone and want something else for calls? Coloros lets you pick from built-in tones, but on dual SIM devices each SIM number can carry its own separate sound. Missing this per-SIM setting is why some calls still ring with the wrong tone even after changing it once.
